NON-ISOLATED DC/DC CONVERTERS POWER PRODUCTS 5V Input / 0.9V – 3.3V Output / 10A BP06VRPB-10B VRPB-10B Series RoHS Compliant • Nonisolated • Industry standard footprint • Fixed frequency • High efficiency means less power dissipation • Excellent thermal performance • Optimized for cost • Remote on/off • Remote sense • Undervoltage lockout (UVLO) • Over current and short circuit protection • Industrial temperature range Description The Bel VRPB-10B modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal 5V source. These converters are available in a range of output voltages from 0.9V to 3.3V. They are packaged in a compact, SIP package rated at 10A. Standard features include remote on/off, over current and short circuit protection, output voltage adjust and industrial temperature range (-40° to +85° C). The output is closely regulated and the efficiency is typically 95.5% @ 3.3V output at full load. These products may be used almost anywhere low voltage silicon is employed and a 5V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment.
